If you heard loud noises around UTSA

The University of Texas at San Antonio conducted a test of the university’s Giant Voice outdoor mass notification system at the Main Campus between 10 and 11 a.m. Friday.

Those on the UTSA Main Campus and the surrounding community may have heard messages on the outdoor speaker system. The test consisted of three tones followed by a brief announcement that it is a test of the emergency notification system.

To prepare the UTSA and surrounding communities for system testing, the university contacted apartment complexes, neighborhood associations, businesses, media outlets, the San Antonio Office of Emergency Management and other officials to provide information on the system and the test.
